IMPROVEMENT IN MOULDIIRS ILASKS.

TO WIIOM IT CONCERN:

Be it known that I, MATTHEW M. DONNELLY, of Cincinnati, Hamilton county,Ohio, have invented a new and useful 4Improvementin Moulders Flasks; andI do hereby declare' the following to be a. full,`clear, and exactdescription thereof, reference being had to the accompanying drawings,making a, pnrt'ofthis specification.

f This invention relates to a. construction of xnoulders flask which`enables one orrboth ends to be set out o1 adjusted, so as to compensatefor the weer of the guide-pins, und thus avoid the disfigurementof a.faulty seam at the line of parting.

The nslc here selected` for illustration is one of three parts orframes, and the peculiar feature of my inven,

tion is the provision of the adjustable end'or ends A, prci`era.bly ofmetal, having flanges B, having slotted or enlarged holes, b, to receivebolts C, whicllren-tering the wooden other sides D, secure the ends tothe desired position, so as to cause the guide-pins E to fit snugly andaccurately in the notches F.

l Should accident or weer oi' the guiding surfaces impair the accuracyof the parting, the defect is instantly remedied by a blow with themoulders mollet on the ends of the flask, sufcient to bring the pins tobear snugly against thc-guidesLpreviously loosening the bolts wherenecessary.

I claim herein annew, and of my invention- I An improved moulders flask,with adjustable ends, constructed in mnnner substantially as and forlthe purpose set'forth. Y v

In testimony of which invention I hereunto set my hand.

MATTHEW M. DONNELLY.
